Cheers YesBrilliant, mattjewell.com is being a little slow right now so it might be acting a bit crap

mtorregiani, i read your post and then forgot about it sorry. I can't seem to find a whois server for .com.es or .es, so i can't add support sorry

 

[mtorregiani]

mtorregiani, i read your post and then forgot about it sorry. I can't seem to find a whois server for .com.es or .es, so i can't add support sorry

Maybe this one: http://ineco.nic.es/cgi-bin/consulta.whois

 

[Matthew.]

Can't work with that sorry :P

There is no whois server listed on any site i can find and whois services like whois.sc d not even give a full whois report so i can only assume it doesn't have one :td:

 

[signor]

this is just what i was looking for,i can't thank you enough!

btw...can you make a bulk GOOGLE PageRank checker?

 

[Matthew.]

Don't mention it signor.

That's actually an interesting idea you havce, i may look into doing that some time in the future, depends when i get some time.

Matt

Matt

yes off course :] :] :]

 

[mtorregiani]

Id it possible to add the .mobi extension?

 

[Matthew.]

.mobi support is already a feature in the last revision mtorregiani

 

[mtorregiani]

Oh, sorry then.

 

[w1ww]

Matthew, *.pt domains that are registered show as available, hmm can you try to fix it ?

 

[Matthew.]

Matthew, *.pt domains that are registered show as available, hmm can you try to fix it ?

Hmm, no in short

Seems .pt does not actually have a whois server, must be in the list by mistake

Sorry, all i can do is remove support for it (will upload updated version in a while)

 

[ILU]

Great, simple install - just download and upload both files

 

[w1ww]

Matthew the whois server for .pt is 'whois.dns.pt'

 

[Matthew.]

Matthew the whois server for .pt is 'whois.dns.pt'

Ah - Well then i take that back. I searched for it myself but wasn't able to find one coming to the conclusion it was one of the ccTLDs without one.

Give me a couple of minutes I'll update the script.

Edit: Script updated! .pt support fixed!

 

[w1ww]

It is working , great job! You may want to add support to *.com.pt it uses the same whois server !

 

[Matthew.]

Awesome I'll be sure to add that later tonight!

 

[Alex.]

if you need to know other whois servers, i can help.

i have a commercial prog that gives you a list of all whois servers as far as i know.

 

[Matthew.]

I'll be sure to let you know if i need any manofgames, most are available on the internet though

 

[mtorregiani]

I didn't downloaded the newest version, but I modified the first one.
Here's the demo: http://www.mtorregiani.info/domains/index.php

 

[Matthew.]

Good stuff mtorregiani

Note: I am aware of the problem with .ORG domains in <= the latest version, i do not have time to investigate this now however will get round to it in the next few days.

(They results are inaccurate after 4 domains when checking all .ORG).

Matt

 

[SNaReX]

Very good script. I was searching for something like that. But I think we need a proxy integration or random whois server system to the script

 

[Matthew.]

Hi SNaReX,

I don't see the need for it as of now as i have had no problems nor any reports of IP banning from the whois servers because of this.

Thanks for the comments

Matt

 

[sukantab]

Thanks a lot again.... This is very helpful update. .in names are very hot nowadays.

 

[Matthew.]

.ORG Support have been removed as multiple requests are blocked from the WHOIS server (PIR).

A solution would to be add a proxy into the script however i am just too busy to do anymore to it.

All other extensions are fine.

Matt

Thank you for the script. I have been using it for the last few days. I hate to report, but the whois look up on "info" whois.afilias.net has a limit that I exceeded. I don't know what the limit is and I don't know if the limit is restored after an amount of time, but woudl like to report that aspect of "info" look'up's.
